Motherboard test machine
A test machine for testing a printed circuit board (PCB) ( 50 ) includes a base box ( 10 ), a top test device ( 70 ), a raising board ( 41 ), and a control system. The top test device is pivotably secured to the base box, for testing the PCB. The raising board carries the PCB to be tested, and is upliftably secured on the base box. The control system controls lifting of the raising board up, thereby connecting the PCB with the top test device during testing.
1. A test machine for testing a printed circuit board, comprising:
a base box;
a top test device pivotably attached to the base box, the top test device comprising at least one peripheral element;
a raising board upliftably supported on the base box, the raising board being configured for carrying the printed circuit board and lifting the printed circuit board toward the top test device to connect the at least one peripheral element with the printed circuit board; and
a rear test device, the rear test device comprises a securing board, a sliding body slidingly installed on the securing board, a test board secured on the sliding body for testing the PCB, and an air cylinder for driving the sliding body with the test board to slide.
2. The test machine of claim 1 , further comprising a control system which comprises an air cylinder under a loading board of the base box, and a driving post connected with the air cylinder and extending through the loading board for lifting the raising board.
